30, 60 or 90-day customers: VAT timing boundary
Convert payment-term assumptions into the percentage actually collected inside one VAT period.
Decision boundary
Average payment days alone do not establish a VAT payment date. The calculator therefore asks for the percentage actually collected in the period.
Evidence to check
- Actual bank-credit, card, cheque or cash payment dates
- Receipts that fall inside the VAT accounting period
- Invoices with terms of six months or more, which are excluded transactions
